Act Four

Act Four synopsis:

Antipholus of Ephesus sends Dromio of Ephesus to buy a rope’s end to beat Adriana. The goldsmith, Angelo, demands the money Antipholus owes him for the chain. Antipholus denies having received the chain and refuses to pay. The goldsmith has Antipholus arrested. Dromio of Syracuse enters with news of a ship on which he has booked passage. Antipholus of Ephesus sends Dromio of Syracuse to Adriana for money for bail.

Dromio of Syracuse tells Adriana about the arrest of Antipholus of Ephesus. She gives him the money for Antipholus’s bail.

Dromio of Syracuse gives Antipholus of Syracuse the money sent by Adriana. The Courtesan enters and demands the chain that Antipholus is wearing. When he flees, calling her a devil, she decides to tell Adriana that Antipholus is insane.

Antipholus of Ephesus, under arrest, beats Dromio of Ephesus for bringing a rope’s end instead of the money for bail. Adriana, Luciana, and the Courtesan enter with Dr. Pinch, who has been employed to cure Antipholus’s reported insanity. Officers bind Antipholus and Dromio of Ephesus, and Dr. Pinch has them carried off. Antipholus and Dromio of Syracuse enter with their swords drawn, frightening Adriana and the others, who think the madmen have escaped from Dr. Pinch.
